Cluster-based organisation is widely used to achieve energy efficiency in Wireless Sensor Networks (WSNs). To achieve confidentiality of the sensed data, it is necessary to have a secret key shared between a node and its Cluster Head (CH). Key management is challenging as the CH changes in every round in cluster-based organisation. In this paper, we propose two schemes for key management in clustered sensor networks with changing CH. In Simple Secure Logical Ring (SSLR) scheme, communication and computation cost incurred for key establishment is constant. In Burmester Desmedt Logical Ring (BDLR) scheme, key establishment is achieved by performing (n + 1) multiplications and (n + 5) communications, where n is the number of nodes in the cluster. Simulation results show that node compromise in the proposed schemes is handled efficiently.
